I know it’s fairly common to write roles for actors and give the character a name similar to the actor’s name (Tim Allen/Tim Taylor, etc)
I know this is not usually done when adapting a book into a movie, because a book is not usually written with an actor in mind, and movie adaptations of books don’t usually change names that much
which is why I find it particularly funny that Ryan Gosling played Ryland Grace
hilarious coincidence, or hilarious list of criteria for audition candidates? who knows
